Also, thanks to the ravenous Koi and Comets who cheerfully lurk in the backyard pond, awaiting the skeeters egg-laying efforts, we have virtually no mosquitoes here.

Sorry..*not* included.
Ivomec Pour On from the farm store for heartworms UNLESS you have -any- kind of Collie/collie mix.
They can’t have Ivermectin in any form.
